Title: Apparatus which can be used in sub-aqua diving and method for its manufacture
Inventor: RAY CLAUDE
IPC: G03B17/08
Filed: 1984-02-02
Abstract: The seal between the lid (2) of the housing of a camera for sub-aqua diving and the body (1) of this housing is provided by a vulcanised lining (8) covering the edge of the lid, and which, during fitting of the latter, is interposed between it and the body (1). This gasket (8) is made in a single piece with annular parts (8b, 8d, 8e, 8f) surrounding openings (7, 4, 5 and 6) made in the lid. The connection between these annular parts and the main part of the gasket (8) is provided by extensions or branchings (8a, 8c) of the lining produced in grooves made in the internal face of the lid (2). Thus, the seal is of a single piece, which avoids the risk of losing parts of it and facilitates the fitting of the lid (2) on the body (1) of the housing. The gasket (8) is obtained in situ by hot vulcanisation. <IMAGE>
Patent CH-681752-A5 (CH)
Inventor: INEICHEN KURT
IPC: H01H71/46
Filed: 1991-02-22
Abstract: A protection switch with sudden switching on and off, a trip-free release and forced opening is described. A manually movable actuator (10) forms with a U-clip (50) a toggle lever. One leg (51) of the U-clip (50) forming the toggle joint axis is displaceably guided in the actuator (10) in a link (15) with a variable spacing from its rotation axis (11) and against the action of a spring (14) supported on the actuator (10). The other leg (52) of the U-clip (50) is guided in a fixed link (25) and in a ratchet lever (40). The ratchet lever (40) serves to transfer movement to a contact arrangement (21, 22) and cooperates with the release ratchet (60) of an overcurrent and/or undervoltage monitoring device. The fixed link (25) controls the engaging movement of the ratchet lever (40). In an intermediate position of the ratchet lever, it has a detent (26), which only releases said other leg (52) of the U-clip (50) following the further movement of the actuator (10) over and beyond the dead center position of the toggle lever (10, 50) and the tensioning of the spring (14) for sudden contact closure. The construction requires a minimum of parts, particularly if the spring (14) is directly shaped onto the actuator.
Patent CH-650622-A5 (CH)
Title: Electrical drive having a DC motor
Inventor: HETZEL MAX
IPC: H02P7/285
Filed: 1980-01-24
Abstract: The electrical drive has a DC motor (4) which is supplied, via a controlled rectifier arrangement (3, 5), directly from the AC power supply with DC pulses of controlled duration. The e.m.f. induced in the motor is determined by a microcomputer (12), in each case directly before the triggering of the rectifier arrangement, and is used to control a variable delay ( tau var) of the triggering time in each case during the following half-cycle. A measurement of the e.m.f. is thus achieved which is uninfluenced by balancing processes resulting from the inductance of the motor winding, which is critical for precise control. <IMAGE>

Patent CH-659380-A5 (CH)
Title: Apparatus allowing the magnification of the image of teeth during dental examination
Inventor: MILNER THEODOR
IPC: G02B25/00
Filed: 1984-06-06
Abstract: The apparatus consists of a support (1) which carries a ring (2) in which a magnifying lens (3) is crimped and which terminates in an attachment ring (4). The apparatus is fixed to the shaft (12) of the mirror (10) by means of the attachment ring (4). It is possible to slide the apparatus along the shaft of the mirror in order to adjust the clarity of the mirror/lens assembly. During normal dental examinations by means of this apparatus, the image of the teeth will be greatly magnified (approx. 3 times), and will thereby markedly facilitate the detection of abnormalities such as caries. Since the lens remains outside the patient's mouth, the apparatus is no more complicated to use than a simple mirror. <IMAGE>
Patent CH-660851-A5 (CH)
Title: Process for continuously thickening suspensions
Inventor: MUELLER HANS DR-ING
IPC: B01D29/15
Filed: 1983-05-25
Abstract: In a process for continuously thickening suspensions which are difficult to filter in a candle filter, the residues on the filter cloth (4) are removed during thickening by a very short back-flush surge into the liquid-filled filter container, which is under pressure. The filtration is interrupted by this for only a few seconds and the thickening can thus take place quasi-continuously. The process is particularly suitable for thickening suspensions of red mud, cellulose effluents and kaolin slurries. <IMAGE>

Title: Band to measure real size of shoes of different styles - as against their nominal size particularly for children's foot-wear has curved graduation marks
IPC: G01B3/02
Filed: 1974-09-10
Abstract: Many shoes of different styles with the same nominal size may have, due to their particular shape or manufacture process, different real sizes. Therefore, for perfect fitting, the real size of the shoes must be measured and may be compared to the size of the wearers foot. The measuring apparatus has a band with curved graduating marks to allow for the change in shape. The measuring band is pierced with transversal holes made with regular spacing, according to each size, which enable the apparatus to be set to several different overall sizes. In other respects, the measuring instrument is constructed according to the usual pattern.
